What does it mean if a liquid is 'hypertonic' to plant cells?.
why is Valparaiso Chile hotter than Sydney Australia if they are at the same latitude?
Answer:
Places at the same latitude may have very different climates if one is on a coast and one is inland. On the coast, the climate is influenced by warm moist air from the ocean. ... Farther inland, the climate is influenced by cold or hot air from the land. This air may be dry, because it comes from over land

An apparatus for measuring thermal conductivity employs an electrical heater sandwiched between two identical samples of diameter 25 mm and length 60 mm, which are pressed between plates maintained at a uniform temperature To = 77°C by a circulating fluid. A conducting grease is placed between all the surfaces to ensure good thermal contact. Differential thermocouples are imbedded in the samples with a spacing of 15 mm. The lateral sides of the samples are insulated to ensure one-dimensional heat transfer through the samples.
Required:
a. What is the thermal conductivity of the stainless steel sample material?
b. What is the average temperature of the samples?
The thermal conductivity of the stainless steel sample material is 30Q/ΔT.
Thermal conductivity
The thermal conductivity of the stainless steel sample material is calculated as follows;
[tex]k = \frac{Ql}{A\Delta T}[/tex]
where;
Q is quantity of heat transferred
l is the length of heat flow = 15 mm = 0.015 mA is the area ΔT is change in temperatureArea = πd²/4
Area = π(25 x 10⁻³)²/4
Area = 0.0005 m³
[tex]k = \frac{Q \times 0.015}{0.0005 \times \Delta T} \\\\k = 30\frac{Q}{\Delta T}[/tex]
Thus, the thermal conductivity of the stainless steel sample material is 30Q/ΔT.
More information is needed on the heat supplied to the samples and the final temperature.

3) why is ozone layer important to us?
(best answer gets to be the brainliest!)
1) Ozone (O3) is a highly reactive gas composed of three oxygen atoms.
2) The ozone layer is the common term for the high concentration of ozone that is found in the stratosphere.
3) It protect us from harmful UV rays and radiation and help to reduce temperature.
Answer:
1. What is ozone? Ozone is a gas that is made up of 3 atoms, and is extremely reactive.
2. Where is the ozone layer? The ozone layer is located in the stratosphere.
3. Why is the ozone layer important to us? The ozone layer is important to us because it protects the Earth from UVB that comes form the Sun.

Which of the following organisms feed on the detritus found in wetlands? a. Aquatic insects b. Birds c. Reptiles d. Predatory fish Please select the best answer from the choices provided A B C D.
Wetlands are the ecosystem that consists of flooded water and includes swamps and marshes. Aquatic insects feed on the detritus found in the wetlands.
What are detritus and their importance?Dead matter or the organic remains of the plant and animal bodies, and faecal matter are called detritus. They are the litter or the waste that gets decomposed by a certain type of microorganisms.
It is an important aspect of the ecosystem as it serves as a food resource for aquatic insects and organisms. The aquatic insects have various feeding modes and habits and depending on their eating habits they acquire their prey and food source.
Therefore, option A. aquatic insects feed on the detritus found in wetlands.

What is the anammox reaction, and when does it occur in the nitrogen cycle?
Anammox (anaerobic ammonium oxidation), which is a reaction that oxidises ammonium to di-nitrogen gas using nitrite as the electron acceptor under anoxic conditions, was an important discovery in the nitrogen cycle.
The nitrogen cycle's anammox reaction takes place when nitrogen compounds are converted back into atmospheric nitrogen gas during the denitrification phase.
Thus, In order to avoid the buildup of too much nitrogen (such as nitrates and nitrites) in the environment, which can result in water pollution and other ecological issues, denitrification is an essential phase in the nitrogen cycle.
Low oxygen conditions, such as sediments in wetlands, wastewater treatment facilities, and oxygen-depleted regions of oceans, are where anammox bacteria carry out the anammox process.
In the end, this process aids in maintaining the balance of nitrogen in ecosystems and preventing nitrogen pollution by naturally removing excess nitrogen molecules from these habitats.
Thus, The nitrogen cycle's anammox reaction takes place when nitrogen compounds are converted back into atmospheric nitrogen gas during the denitrification phase.

What biological concept was mendel studying when he crossed pea plants many times over many generations?.
Answer:
Inheritance Patterns
Explanation:
Mendel was studying how genes are past on to future generations and in what circumstances this can occur. He used pea plants as they multiply and grow quickly allowing him to observe many generations much faster than he would be able to observing humans or even other mammals. He also used pea plants because this way he could control reproduction of his pea plant population to adjust to specific questions he had in terms of his research.
